Migration from other solutions

This is just an outline, please help completing this page with more details.

It is quite easy to migrate from many other "media" solutions to Scald.

General purpose methods

From IMCE/embedded images modules

Get a list of used files from the text fields/from the {files} table and create scald_image atoms. Enable MEE module.

From File Entity based modules

Add an atom for each file, use hooks to create new atom when a file is added.

From File Field modules

Use Atom Reference module.

From nonexistent module

Just install Scald module.

Using Migrate module

Scald support Migrate out of the box using Migrate/Migrate Extras modules. For example, with destination is Scald atom of type image, provider scald_image:

    $this->destination = new MigrateDestinationEntityAPI('scald_atom', 'image');

    $this->map = new MigrateSQLMap($this->machineName,
      array(
        'sourceid' => array(
          'type' => 'int',
          'notnull' => TRUE,
        ),
      ),
      MigrateDestinationEntityAPI::getKeySchema('scald_atom')
    );

    $this->addFieldMapping('title', 'title');
    $this->addFieldMapping('type')->defaultValue('image');
    $this->addFieldMapping('provider')->defaultValue('scald_image');
    $this->addFieldMapping('scald_thumbnail', 'field_node_gallery_image_fid')->sourceMigration('Files');
    $this->addFieldMapping('scald_thumbnail:file_class')->defaultValue('MigrateFileFid');
    $this->addFieldMapping('scald_thumbnail:preserve_files')->defaultValue(TRUE);
